[eternal oxide]

near teh botton is using multiple configs

what class you put them in is upto you

you do not need to make a string object for every entry in your config

[regal scaffold]

I didn't ask "Using custom configurations".

Do you guys use built in fileconfiguration to do your big configs?
Or what good alternatives is there

Meaning I know how to do with with that resource but I was wondering if people use different resources for that

[eternal oxide]

the config is already loaded into memory so it already contains ALL of your strings in a map

[regal scaffold]

Currently I'm using a combination of getConfig() where I need it and storing the paths somewhere

But just doesn't seem the best using that every single line there is a message for example

[eternal oxide]

A constants file for paths

[regal scaffold]

Yup

That's what I have

So that is what's recommended then

[eternal oxide]

thats what I often use

[regal scaffold]

Hmmm

[eternal oxide]

simplifies fetching config data and a single point to modify paths

[regal scaffold]

Yeah that is true

Does a Map#get() loop through every element in the map? I assume that's really inefficient

[eternal oxide]

it does not

[regal scaffold]

Is that not a good alternative? key -> value?

[eternal oxide]

how you access yoru map is upto you

[regal scaffold]

Yeah you are right about that

[eternal oxide]

a Map stores by Hash value

[lost matrix]

Really depends on the implementation of the map.
But i dont know a Map impl where this inefficient approach is used.
Generally you would use a HashMap which uses hash buckets underneath
to provide a O(1) time complexity. This means the map will be as fast with 10
elemts as it is with 10.000 elements.
You can read more about that in 3.1 of this forum post where i explain
shortly how time complexity works:
https://www.spigotmc.org/threads/guide-beginners-guide-on-improving-your-codes-performance.396161/

[regal scaffold]

I see, but how do you implement configurations + lang

Do you do anything different to what's in ?config

[smoky oak]

do it on chunk load and its a very minimal thing

[regal scaffold]

Do you getConfig# every time you need something? Do you store it somewhere?

[wet breach]

Caveat should be noted as you increase in elements if the buckets dont increase or you get an odd amount of elements and either have too little or too many buckets you will have degraded performance and even there is still a limit only because there isnt infinite time lol

[lost matrix]

I generate my language files dynamically. There are different approaches but i would not
write my lang files from hand. In this case i used an enum, write the default values in there
and let the user translate what is needed in the generated language file.

[regal scaffold]

Ok yeah perfect

[lost matrix]

Yes i was ofc assuming no collisions

[wet breach]

However most people dont need or shouldnt need to worry about time complexities until it is an issue

[regal scaffold]

But then, do you access it like I said above? getConfig#getString(Translation.Whatever)

[lost matrix]

No. I never access any config files after my plugin is enabled.
I load everything into concrete classes.

[regal scaffold]

Ok that's exactly what I thought

Do you store stuff in a list of strings? hashmap?

[lost matrix]

In this case i use an enum

With a mutable field

[wet breach]

Or you turn that data into an object

[lost matrix]

Last line shows translation usage

[regal scaffold]

ooooooo

Alright alright, thanks a lot. That showed me exactly what I needed to know

[lost matrix]

But explore a bit. Translations are always a hustle. Ive also used a system where i literally
replaced text in outgoing packets because i could just be really lazy in my code and
not worry about translations. But that felt a bit hacky.

[regal scaffold]

I see

I like what you did with translations

Do you do something similar with config values?

[wet breach]

Just dont over use enums

[regal scaffold]

Yeah

[wet breach]

They are handy but they do come with a catch for using them lol

[regal scaffold]

What's the catch?

Can't leave me hanging like that

[wet breach]

Enums are static

Stuff too many in a single class and you enounter various issues optimizations by the jvm being among the few lesser known ones

[regal scaffold]

Alright fair, gotcha

Smile how do you load the values into the enum?

I assume your Message.sendInfo# method gets the value

[wet breach]

You just put the value in the parenthesis

Have an example

[regal scaffold]

lol I know that

I mean

His first parameter is path, second is default

Path doesn't convert automatically to the config value

So I assume his Message#sendInfo method does that call

[remote swallow]

he probably modifies it on startup

[wet breach]

https://github.com/frostalf/ServerTutorial/blob/master/ServerTutorial/src/main/java/pw/hwk/tutorial/enums/Permissions.java

[regal scaffold]

Wait wut

[remote swallow]

im guessing from his var names, that enum gets loaded into translations.yml on start up if not exists, if it does it just modifies the enum

[regal scaffold]

ooooo

[wet breach]

You can put objects in an enum

[regal scaffold]

So he replaces the path with the value on startup

[remote swallow]

probably the value

[wet breach]

Thr enum cant change but the object can

Or the value as its better known like epic said

You can even use an enum to create objects too

[regal scaffold]

Ok ok time to code a bit

[wet breach]

Just stuff inside the enum new whateverobect() lol

[ivory sleet]

Use resource bundle api if u gonna go with a language locale thingy

[small current]

How to check if an itemstack can be placed when right clicked?

[rotund ravine]

Omg

Lowercase

Reeeeee

[eternal oxide]

pitchfork time!

[remote swallow]

phon prob

[orchid gazelle]

[echo basalt]

Material#isBlock

[small current]

is ender crystal a block?

[echo basalt]

uhh

that's specific

wouldn't say so

it's also only applicable under certain circumstances

[green falcon]

anyone know a good plugin to store arbitrary persistent user data and sync it across multiple spigot instances? I saw HuskSync looks like a somewhat decent solution but also MySQL Player Data Bridge

[tender shard]

what issue?

it's working fine

[eternal night]

alex back

[rough drift]

Is there any way I can replicate the effect of clicking on a sheep with wheat?

I came up with

if(entity instanceof Breedable breedable) {
  breedable.setBreed(true);
  // play effect
}

This should work right? Though some mobs that extend Animals such as Sheep have loveModeTicks

I figure that setting breed to true will override that

[wet breach]

to be fair, I was on my phone

lots of stuff goes out the window when I am on my phone because it is too much of a pain otherwise lol

[remote swallow]

[river oracle]

Hi alex!

[regal scaffold]

Man, Copilot is nuts

[remote swallow]

activate windows

[regal scaffold]

It's so smart

I format too often cba

[remote swallow]

it saves the key to ur microsoft account

[regal scaffold]

Not after years

[remote swallow]

ah

[tender shard]

wazzup

[regal scaffold]

Hey, I have reached another "issue"

My placeholder manager

Currently I have like 40 placeholders for everything. But this method is getting kinda crazy, it's so big now

        placeholders.put("%current_upgrade_members_tier%", ultraChest.getCurrentUpgradeMembersTier());
        placeholders.put("%current_upgrade_members_value%", ultraChest.getCurrentUpgradeMembersValue());
        placeholders.put("%next_upgrade_members_tier%", ultraChest.getNextUpgradeMembersTier());
        placeholders.put("%next_upgrade_members_value%", ultraChest.getNextUpgradeMembersValue());

imagine that but 50 instead of 4

What can I do to manage this better

PlaceholderAPI is not an option*

[green falcon]

extra verbosity is readability really ya? thats why we have code folding

[ivory sleet]

Not always

[hazy parrot]

I use reflection in kotlin, not sure if that will be reliable to you

 @Suppress("UNCHECKED_CAST")
    private fun <T> getPlaceholderMap(entity: T): Map<String, String> {
        val fields = entity!!::class.members
            .filterIsInstance<KProperty1<*, *>>()
            .map { it as KProperty1<T, *> }.filter { it.visibility != KVisibility.PRIVATE }
        return buildMap {
            fields.forEach {
                val value = when (val uncheckedVal = it.get(entity)) {
                    is Float -> String.format("%.2f", uncheckedVal)
                    else -> uncheckedVal.toString()
                }
                this["%${it.name}"] = value
            }
        }
    }

and entity being for example

data class NodeInfo(private val node: Node, private val nodeStatus: NodeStatus, val runningServers: Int, val ramUsed: Long, val diskUsed: Float, val cpuUsed: Double) {
    val name = node.name!!
    val description = node.description ?: ""
    val location = node.retrieveLocation().execute().shortCode!!
    val maintenance = if (node.hasMaintanceMode()) "On" else "Off"
    val allocationsCount = node.retrieveAllocations().execute().size
    val ramLimit = node.memoryLong
    val memoryUsageBar: String
        get() = MemoryBar(ramUsed, ramLimit).toString()
    val diskLimit = (node.diskLong.toFloat()) / 1024
    val status = nodeStatus.message
    val statusEmoji = nodeStatus.emoji
}

according to that, for example "%status" will resolve to nodeStatus.message

[regal scaffold]

Jesus

[regal scaffold]

@lost matrix You use ACF in all your plugins right

[native gale]

Is there a way to deduce, how many exp will renaming an item take?

[regal scaffold]

wym?

[hazy parrot]

Copilot is probably most hyped and least useful tool I ever encountered

[regal scaffold]

No way

tf

[lost matrix]

Pretty much

[regal scaffold]

Still debating if using it or just using bukkit impl

[rotund ravine]

I mean

It’s nice

Nicer than bukkit

[hazy parrot]

I never found it useful aside for simple copy, paste tasks, I even disabled it rn because it's pretty annoying to always suggest crappy code

[regal scaffold]

Well yeah

The options are

Doing that or using acf

[lost matrix]

Look for a decent command lib or write your own. But Bukkit has such a barebones approach that
i would never use it as is.

[regal scaffold]

I mean ACF is considered a decent command lib as far as I know

Definitely seems fine if you don't dig too deep

[lost matrix]

It has a steep learning curve and is really hard to master

[regal scaffold]

A bit confusing at the start

I can tell

Like I'm just staring

At idk wtf

What's confusing me rn is how can you have a command with any parameters, where is it even getting those parameters from

    @Default
    @Subcommand("list")
    @Syntax("<+tag> [page] or [page]")
    @CommandCompletion("@residencelist")
    @Description("Lists all of your or another players residences.")
    public static void onList(Player player, String[] args) {}

For example

That's what acf is

It's an example from their wiki. I'm just trying to understand it

[lost matrix]

You need to look into context resolvers. They are used to resolve an argument (String) into
an instance of your parameter (T)

[regal scaffold]

Ahhhh I see that part now

[lost matrix]

And String[] is something i have never used in acf

[regal scaffold]

Straight from their wiki so idk

https://github.com/aikar/commands/wiki/Real-World-Examples#:~:text=public static void onList(Player player%2C String[] args) {

wym no

It's literally straight from the wiki

[native gale]

Sorry, I think you misunderstood me. What I mean is ```java
double deduceExp(ItemStack stack, String name) {
// returns how many EXP will it take to rename the item
}

[regal scaffold]

idk why he uses it but yeah, odd

https://github.com/aikar/commands/blob/master/core/src/main/java/co/aikar/commands/CommandContexts.java

What

the f

Ok I sort of understand contexts

[lost matrix]

Those are the default context resolvers

[regal scaffold]

yeah yeah I noticed

So pretty much they have a way to convert parameters straight into "objects"

I mean it's kinda cool

I gotta be honest tho

You can tell aikar makes libraries and not plugins

Bukkit implementation it is

It's so massive

Wait so @lost matrix What you're saying is

I can have a command like /block add

That will automatically get the block the player would be looking at using custom context resolvers

So I will have the block as parameter from the start

[remote swallow]

you shouldnt need a context resolver for that, you just get what block the player is looking at

if you have /block add MATERIAL you would need a context resolver iirc

[regal scaffold]

Oh you are right, I checked it the wrong way

[remote swallow]

you also can use just Player player, instead of CommandSender

[regal scaffold]

If I have an enum with

NAME("path","value");

How do I populate the "value" field on startup

[brave sparrow]

What do you mean

[regal scaffold]

I have an enum containing elements that have a path field ( preset ) and a value field ( startup ) to get stuff from my config file.

I want to assign the correct value to each element on startup from the config using their own path value

But since it's an enum I'm a bit confused on how to do that correctly. I know how to get the value I just don't know how to correctly assign it

[brave sparrow]

You do it in the enum’s constructor, but you need to make sure the enum doesn’t get referenced until after the plugin is loaded

[quasi flint]

why enum?

[regal scaffold]

Oh ok! I got it then

So if my enum is called ConfigPath

    ConfigPath(String path, String value) {
        this.path = path;
        this.value = plugin.getConfig().getString(path, value);      
    }

That would do the trick right?

Or alternatively I could just do it every time I need it instead

[eternal oxide]

add a getValue method to the enum

[brave sparrow]

I would say you should have it cache once you’ve retrieved it once

[regal scaffold]

Gotcha

[brave sparrow]

You don’t need to be fetching it every time, but you also don’t need to fetch it all at once

[regal scaffold]

Now I'm thinking tho...

What if some of these values aren't a string but they're something else like a StringList

[eternal oxide]

fetching from config is fine as that is already in memory

[regal scaffold]

Then I can't do it this way

[eternal oxide]

it's just a map lookup

[brave sparrow]

If the values are going to be that varied you probably shouldn’t do it that way

You can

[eternal oxide]

This was not in your design pattern when you were told to use an enum

[regal scaffold]

Yeah yeah I got it

Different things

This is a path

Just the path

I should make a different thing to get whatever is behind it

Which could just be getConfig()#getWhatever

Can't mix them up

[brave sparrow]

Alternatively you could do it with just the path I guess

It wouldn’t be the cleanest thing

But you could do something like

[regal scaffold]

Well if I have an enum of paths, I can just use getConfig()getList(Enum.WHATEVER)

[brave sparrow]

public <T> T getValue(Function<String, T> configLoader)

[regal scaffold]

And if I want I can make something to summarize getConfig()getList into more stuff I need

[brave sparrow]

But you probably don’t need to do it that way lol

[solar mauve]

https://pastecode.io/
paste here, use java syntax, i can't access md-5.net for some reason

[analog thicket]

I fixed the circle getting bigger and bigger, but everything is just off about the stuff. So I'm starting over.

[tawdry cedar]

Using Simple-Yaml and Java Swing btw

[eternal oxide]

you need to load the yaml file before you add to it

then save

[tawdry cedar]

Did I really forget that 🤦 LOL

Thank you

[17:03:59 INFO]: [[Simple Hide and Seek]] Disabling Hideandseekplugin v1.0-SNAPSHOT```
Heya, I've created a 1.17.1 plugin and trying to run it but it isnt working and disables with this error, i get no errors in IntelliJ, any ideas on a fix?

[brave sparrow]

You can’t make a new instance of your plugin class

[brisk estuary]

Hey. I want to create a custom item that disappears after some time. Does anybody know if it is possible?

It must disappear even if it is inside a chest

[dry yacht]

It surely is possible, but I don't think it'll be trivial. You basically have two options: Either track the item to always know it's location (inventory/container, chunk if it's dropped) or scan all possible containers and entities of all chunks ever created, which is... not really viable.

Another third way, which would be easier, is to just destroy the item when it's used, as that also effectively limits it's lifetime. Who cares if it's in some sort of chest, if it cannot be used or even taken out of the chest without being removed.

[eternal oxide]

store the creation time on the item (PDC). Start a timer, delete it when the time runs out (if held by a player). listen to InventoryOpenEvent and delete any expired items.

[visual laurel]

I fixed that error and now im getting this error instead:

[brave sparrow]

?paste

[undone axle]

https://paste.md-5.net/

[brave sparrow]

Paste it there

[dry yacht]

That basically means that the event will have to scan all slots of all containers always, scan each of their PDCs, to find items marked for removal. That sounds expensive.

[brave sparrow]

No

[eternal oxide]

it only has ot scan for a specific item and check a byte on it's PDC IF found

[brave sparrow]

You only check the chest they’re opening

[visual laurel]

https://paste.md-5.net/hohunizeve.cs

[brave sparrow]

Not all containers always

[eternal oxide]

yep, only each chest as it opens. not a heavy load

[brave sparrow]

Show us your onEnable

[dry yacht]

Yeah, I get that, but you're still having to do that for all chests opened, as you don't know this ahead of time. So all ever opened chests will get a full scan.

[brave sparrow]

It’s not expensive because you amortize it over time

[brisk estuary]

Thanks for the tips guys

[eternal oxide]

yes, still not a heavy load. hardly any at all

[brave sparrow]

Ok, let’s see your HiderFoundListener

[visual laurel]

https://paste.md-5.net/yezidefaka.java

[brave sparrow]

Aha

Ok now HiderFoundEvent please

[visual laurel]

https://paste.md-5.net/otijayeliy.java

[brave sparrow]

That’s your problem

The handler list methods are returning null

[pseudo hazel]

you need a static handler list which you forgot

[brave sparrow]

https://www.spigotmc.org/wiki/using-the-event-api/

[dry yacht]

Didn't say heavy even once. I called it expensive, which it is. It's total overkill. If the item offers some special effect, just remove it when it's trying to be used after it's lifetime elapsed and notify the player. That's a compromise to not increase workload on every chest block container opening. What if the player keeps it in their inventory? Do you also scan inventory slots on every chest opening?

This decision is up to the person who asked the question tho, so I guess it has been answered plenty already.

[brave sparrow]

It’s not expensive at all

[dry yacht]

Great mindset. Death by a thousand cuts, :).

[visual laurel]

ah yeah, thanks

[brave sparrow]

Premature optimization is the root of all evil

[pseudo hazel]

well I think there is a middleground between premature optimization and setting yourself up for failure

[dry yacht]

It's called non-pessimization, not optimization. Optimizing is something completely different.

[brave sparrow]

There is

[dry yacht]

Whatever, not going to pollute the chat with this kindergarten anymore. The person who asked needs to decide on their own.

[brave sparrow]

And scanning 30 slots is not going to have any measurable difference on the performance of the server

[dry yacht]

Because you have to do that on all ever opened containers, for no good reason whatsoever.

[pseudo hazel]

if you can easily solve the problem with a less expensive method you should go for it

[dry yacht]

Yes, for ever from the point on that the feature got implemented

[brave sparrow]

You’re not easily solving the problem, you’re sacrificing part of the solution to avoid a minor execution

[dry yacht]

It's not a do once thing, as you don't know how many of these items are around

[pseudo hazel]

okay well then I read wrong

[dry yacht]

If they do know and it's only temporary, that's another thing. I'm not so sure about that tho

[pseudo hazel]

well maybe all existing ones are just shite

[dry yacht]

I was just proposing the idea that removing the item when it's used is cheaper than checking on every container opening, as they probably already have a routine for use detection in place.

If you don't agree with that, it's either personal preference or ignorance.

[brave sparrow]

Avoiding 30 cheap if statements is a micro optimization at best

[dry yacht]

I don't care if it's micro, but it should be the first thing coming to mind to somebody who uses their brain while programming.

[brave sparrow]

If they want the item to vanish when it expires then having it disappear on use is not the desired effect

[brisk estuary]

The item I want to implement is basically a resource used in other recipes. It must expire/disappear after 1 day.

[dry yacht]

I said that it's a compromise. It's up to Voper to decide.

[brave sparrow]

If they want it to expire and it’s trivial to make it expire with no real cost, there’s no reason to have it not expire

[dry yacht]

So you can either make it disappear so that nobody could ever see it again, or you just make the workbench eat it up if it's lifetime elapsed. This is totally up to you, as you now know both ways.

[pseudo hazel]

whats the difference, the item will be destroyed in any case no?

[brave sparrow]

^

[pseudo hazel]

oh I see

yeah

[brave sparrow]

It’s also still taking up space in their chest until they actively get rid of it

Which I can see being fairly annoying in large quantities

[pseudo hazel]

plus it would not be as bad if there are multiple of those items in a container, then its no performance loss to loop through the container as you need to check them all anyways

[brave sparrow]

There’s not really a performance loss anyway

The maximum size of an inventory is 36

[pseudo hazel]

well not really but I get your point

[brave sparrow]

You’re running it on a redstone computer if that causes you issues

[pseudo hazel]

lmao

i think byte wasnt suggesting it would impact your performance to do one loop

its just like a mindset thing ig

[brave sparrow]

It’s premature optimization

There’s no reason to sacrifice functionality when the desired implementation comes with no actual cost to it

[pseudo hazel]

okay

[brave sparrow]

It’s not a matter of implementing it with care and not doing things unnecessarily, it’s a matter of actually not implementing it and implementing something similar to avoid checking 36 slots when a chest opens

[pseudo hazel]

anyways i think we solved the problem

[brave sparrow]

I agree

ouch that's going to be slow

Looks like jycraft hasn't been updated in 8 years

[quaint mantle]

Lol but in 8 year past , make command is Available !

[eternal oxide]

if you know Python it's not a great leap to Java

[pseudo hazel]

yeah I wouldnt use that xD

and just start using java instead or make another project haha

[vocal cloud]

The lengths python devs will go to not touch grass

you're starting to spawn entity from a wrong location, please take a deeper look at my code

this time, you are rotating around z axis

learn math bro, there are plenty types of tutorials out there about sin, cos, vectors, dot product, equations, and stuff

take a careful look at your video, see how your shape is floating at 90 and 180 degrees

ok anyways

is anybody familiar with minecraft skins?

what is the color limit for a minecraft skin?

24 bits? 32 bits? 64?

or 256 highcolor?

[analog thicket]

Well the one you replied to is fixed. I only had one error and that was a little jump in the start of my animation. (In another video way up)

[solar mauve]

and yea choco is right, make radius constant

[solar mauve]

wait

[tardy delta]

gotta learn python for ai 🥹

super().__init__(0, -1) 🥹

[solar mauve]

WorldServer world = ((CraftWorld) player.getWorld()).getHandle();

stand = new EntityArmorStand(world, center.getX(), center.getY() + 3, center.getZ()); // instantiate with a defined position
stand.n(true); // set marker (tiny)

conn.sendPacket(new PacketPlayOutSpawnEntityLiving(stand)); // spawn object
conn.sendPacket(new PacketPlayOutEntityMetadata(stand.getId(), stand.getDataWatcher(), true)); // send metadata

idk, i am spawning it like this, maybe there are some differences between versions in spawning and setting locations, idk...

[rare flicker]

does anyone know an use case for PotionEffectWrapper?
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/potion/PotionEffectTypeWrapper.html

[eternal night]

that is the API way of implementing PotionEffectType for the static constant values you get via PotionEffectType

[tardy delta]

i learnt what enums are today in college 💀

[tardy delta]

teacher asked me "oh is this easy for you"

[rare flicker]

i'm struggling to see the use though since you can just instantiate a new potionEffecTtype

[rare flicker]

bruuuuuh

[eternal night]

what ?

when you create a potion effect

[analog thicket]

Yeah im thinking it has something to do with the animation before that one. There was an up animation before the rotating

[solar mauve]

or you spawned it at a wrong location

[eternal night]

PotionEffectType is abstract because it is also implemented internal in the server (for some reason)

[analog thicket]

I found out it was there was an extra 1 on x. Didn't find out why tough.

[thorn crypt]

Yo, I’m trying to make a thing that when you right click a armorstand it open a GUI and you can edit some thing, but what is the best way to store the clicked armorstand to make edit on it when I do inventoryclick event ?

[eternal night]

store the uuid of the clicked armor stand in the inventory holder

retrieve it on click

[thorn crypt]

I’ll try that, thank you

[rare flicker]

i get that but you can still do this

public static final PotionEffectType SHIVERING = new PotionEffectType(0, new NamespacedKey(OMCPlugin.i, "someKey")) {
    
    @Override
    public boolean isInstant() {
        // TODO Auto-generated method stub
        return false;
    }
    
    @Override
    public String getName() {
        // TODO Auto-generated method stub
        return null;
    }
    
    @Override
    public double getDurationModifier() {
        // TODO Auto-generated method stub
        return 0;
    }
    
    @Override
    public Color getColor() {
        // TODO Auto-generated method stub
        return null;
    }
};
public void applyPotionEffects(Player p) {
    p.addPotionEffect(new PotionEffect(SHIVERING, 60 * 20, 1));
}

[eternal night]

yea

is that pretty to do for all potion effect types ?

no

is hence a simple implementation useful ?

yes

[hexed falcon]

for some reason this cooldown isn't working, is there something wrong with the code?

[rare flicker]

oh

OOOOHHH

okay i got it

[eternal night]

[rare flicker]

you can't really extend potionEffectType and have a static instance cleanly

wait yes you can

[livid dove]

just got back from work so couldnt keep the topic going.

To clarify what I was asking is less "We wanna make this utterly work ayeeee" and more "We know it can effect tps, but removing AI and collision hypothetically should remove most the TPS issues, are there any other issues we are missing before we go and do the funni plugin writing"

[eternal night]

[tardy delta]

that looks like code my teacher writes

man i saw some weird code in class today

[eternal night]

[orchid gazelle]

[hexed falcon]

weird, i'll check the rest

[tardy delta]

public class cooldown which holds a map of cooldowns 🤔

[livid dove]

Before u do u havent said the most important part

What are you wanting it to do and where is it called ?

[hexed falcon]

It's supposed to put a 1sec cooldown after the item is used

this is where it should be used

[livid dove]

Oh boy weve got quite a bit to unpack here

[thorn crypt]

How do I use the InventoryHolder ? I don't find out how to use them 🤔

[eternal night]

||https://docs.papermc.io/paper/dev/custom-inventory-holder|| might work as a tutorial

[pseudo hazel]

why spoiler

[eternal night]

because its a paper link 😅

[thorn crypt]

x)

[remote swallow]

banned

[livid dove]

Question 1:

Your setupCooldown method. What is it declared as. A public static.... something....

What does that something mean

Question 2: Is it a global cool down for every player (one player does it, everyone gets a cooldown) or is it per player?

Question 3: if question 2's answer is "per player" why are you attempting to "setup a cooldown" the moment the server is booted up?

Steaf

its to help em out

i know

[pseudo hazel]

oh

I thought you asked the question xD

[twin venture]

hello , quick question , about InventoryClickEvent
Inventory clickedInventory = event.getClickedInventory();
if (clickedInventory instanceof PlayerInventory ||
clickedInventory instanceof AnvilInventory ||
clickedInventory instanceof EnchantingInventory) {
return;
}

is there one for EnderChest?

EnderChestInventory?

[livid dove]

Nah Im helping him out by gettin em to think about it

[pseudo hazel]

yeah I see now haha

[frosty cairn]

hi, if i folow this guide after enabling iptables and doing the comand the server become inaccesible

[tawdry parcel]

What's wrong with that? name.playSound(Sound.ENTITY_EXPERIENCE_ORB_PICKUP, 1f, 1f);

[livid dove]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/inventory/InventoryType.html#ENDER_CHEST

[thorn crypt]

I don't understand how InventoryHolder work can someone explain me how do I store armorstand's uuid in it and retrieve it ? 🥲

[frosty cairn]

I do this comand
iptables -I INPUT ! -s ip -p tcp --dport 25560:25570 -j DROP
then
dpkg-reconfigure iptables-persistent

[hexed falcon]

Question 1: A: Uh, Public static void which means it will make a space in memory automatically, Question 2: A: per player. Question 3: A: I'm not sure, ive never done this before lol.

[livid dove]

And fgs save that documentation as it is the most valuable tool in ur tool kit

[pseudo hazel]

do you have a custom class that extends InventoryHolder?

[thorn crypt]

Yes sir

[twin venture]

i dont think its avillable for me ?>?

[eternal night]

inventory type is not the same as inventory

[pseudo hazel]

make a new variable called like armorstand of type uuid

[livid dove]

Brilliant okay fantastic.

I get to answer question 1 by saying erm: wrong?

Void is what is returned. Legit think about the word "void" .... what do you think "void" returns?

[thorn crypt]

like that ?

[pseudo hazel]

and then just put the armor stand uuid in it, which should be easy enough

what does static mean

[eternal night]

the inventory interface is only implemented for inventory types that need their own interface

[thorn crypt]

My bad I removed it

[hexed falcon]

Nothing, so should I remove the void?

[eternal night]

an enderchest is just a normal chest in regards to the inventory size

[thorn crypt]

@pseudo hazel

[pseudo hazel]

and then I think you can get it back when you use world.getentity(uuid) or something

[livid dove]

but you see now u have a problem. You are gonna return something but erm... during boot up? U want it to record a cool down the moment the server runs? That dont sound right does it? :S

[pseudo hazel]

yes something like that

keep in mind java code style would be armorstandUuid or armorstandUUID

no underscores

[thorn crypt]

Ok

[hexed falcon]

No, so then what should I change?

[pseudo hazel]

but thats basically it

[twin venture]

so how i can do the check for the EnderChest?

[eternal night]

Inventory#getType

[pseudo hazel]

since you made it private you need getters and setters to actually get the object

[eternal night]

returns you an InventoryType

[livid dove]

No so then what should I change

[thorn crypt]

Yo I got a problem, when I compare the inventory with the created inventory if another player open the inventory, the old player can take every item in it

[eternal oxide]

You are not tracking who has the inventory open correctly. You can get the viewrers

[thorn crypt]

How can I fix it to track who has the inventory opened correctly ?

[eternal oxide]

the click event should tell you who clicked

[thorn crypt]

That doesn't really help me, and even if I got who view it (I have it) how do I see if the player can click in even after another player opened it ?

[eternal oxide]

its your inventory so you need to keep track of who can or can;t use it

[quaint mantle]

Any way to get the amount of a block of type broken by a player starting from a certain timestamp?

[eternal oxide]

not unless you track it

statistics are totals

[quaint mantle]

Can I just store the value in the pdc of the player?

[ivory sleet]

I mean yeah you can

[quaint mantle]

Would you reccommend doing it though?

[hazy parrot]

It really depends on your use case

If it doesn't need to be persistent, you can just use map

[quaint goblet]

yo
does worldguard guard the whole world
or can i select certain regieons

[quaint mantle]

I do. Yeah, thanks.

[orchid gazelle]

@quaint mantle can I get more FPS IRL now?

[hazy parrot]

Region, but pretty sure you can set global flags

[rare flicker]

How can i accurately check if a player is in water?
currently i check for waterlogged blocks, but have to manually check for : Water, kelp, seagrass, tall_seagrass, bubble columns

is there a way to automate that?

[remote swallow]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Entity.html#isInWater()

[rare flicker]

since when ; -;)

[quaint mantle]

... What?

[orchid gazelle]

You are called sodium

[quaint mantle]

Do server freeze when async task calls method from another class?

[quaint mantle]

I didn't laugh at your joke

[orchid gazelle]

Ok

[orchid gazelle]

Everything called in your async task also is async

[hazy parrot]

If task is ran async, it will be async

[quaint mantle]

Oh ok

[orchid gazelle]

But you can schedule sync tasks in your async task if you want

[rare flicker]

oh i remember why i didn't use this actually

this returns true if the head is above water

[remote swallow]

there location is there feet so it probably bases it off that

[orchid gazelle]

What you are looking for is to check if the player is UNDERwater, not IN water huh?

Then you can just use your location and write a method to compare the Type to all the Types you want

[echo basalt]

under water is checked by getting the eye location and seeing if it's equal or below the water line

so you'll need to check for water levels for that stuff

you can simplify half the process and the cheapest check is probably a isSwimming check

[granite burrow]

Is it possible to access the spigot Web API from a webserver (not associated with the Minecraft server)

[opal juniper]

not unless you make it possible

[opal juniper]

meh that only refers to the swimming pose though no?

[dry yacht]

Depends on how you define "possible". There are many ways to define a common API which makes accessing everything you need possible, but as soon as you expose something mighty on the internet, you'll have to think about security as well.

[granite burrow]

I want to get the information from my spigot account to display on a website/discord bot how much plugins I have made with links to each. I know its possible to get that using the Xenforo Resource Manager API, however, it doesn't seem to work on website when I tired it

[dry yacht]

I think illusion ment to use this boolean value as an early return before going into the calculations of eye-hight, block-getting as well as waterlog checks and the like. It would keep a lot of code from needlessly executing while swimming in big oceans, for example.

[dry yacht]

Ohhh, I'm sorry, I completely misread your question. You want the spigotmc.org API, not your spigot server's data.

[granite burrow]

yeah

[dry yacht]

What data is it that you need? That will decide the way you'll have to handle it

[tawdry echo]

what look sorted list of eventpriority by weight

[granite burrow]

I want to get all my uploaded resources data, which I have the link to do everything with. I've done similar things with plugins for testing. However, whenever I do anything outside of the server (aka outside the SpigotAPI) the API throws the following error:
(Reason: CORS header ‘Access-Control-Allow-Origin’ missing)

idk if im allowed to share links here so I didnt post the link I used to get that, but its just using the getResourcesByAuthor part of the API

[dry yacht]

I've used https://spiget.org/ before, which basically crawls spigot and caches the results, as far as I know. It's a nice API, which should allow you to list your own resources. It also should have a CORS wildcard on it's responses.

[echo basalt]

it's half the work

[echo basalt]

correct, always run the cheapest checks first

[granite burrow]

Okay i'll check it out 😄 thank you.

Sad that we can't use the already setup spigot web api

[quaint mantle]

I success to recevie byte[] from forge client, but how to decode it? I tried with ByteArrayDataInput in = ByteStreams.newDataInput(message); String subchannel = in.readUTF(); but it not work, it return java.lang.IllegalStateException: java.io.EOFException tried byte[].toString() and String subchannel = new String(byte[], StandardCharsets.UTF_8); but it return ☻UnpooledHeapByteBuf(ridx: 0, widx: 32, cap: 32/32)

[dry yacht]

I didn't even know that spigot had a public API itself. Where did you get documentation on it? Or have you just checked browser traffic and found the endpoint this way? I'm currently not sure whether spigot is rendered serverside, thus the question.

[echo basalt]

EOFException ocurrs when you try to read data that kinda doesn't exist

Byte streams aren't like json where you know what's the next key type

If you try to read an int (32 bits aka 4 bytes), and only have 2 bytes left, you reach an EOFException

If there's no UTF data, and you're trying to read UTF data, you'll face an EOFException

I'd probably study the forge protocol a bit more before trying to read data blindly

[quaint mantle]

this what i send from client byte[] bytesTask = "mot hai ba bon// nam// sau// bay".getBytes(StandardCharsets.UTF_8); PluginMessages.sendMessage(new BukkitPacket(new FriendlyByteBuf(Unpooled.wrappedBuffer(bytesTask))));

[echo basalt]

Hmm

Seems like you're just wrapping the bytes

Actually I'm not sure how the BukkitPacket class works

I'd probably do a writeInt(array.length), writeArray(array)

and then just

byte[] array = new byte[readInt()]

and read the contents

[quaint mantle]

BukkitPacket is just my custom class nothing inside, it just for forge client

[echo basalt]

Are you sure that your buffer is actually being written then?

You could just be creating a buffer and never actually writing the packet

I don't have much context to work with

[quaint mantle]

but the message.toString() return some string, message is byte[] what recevied from forge client,

[solar mauve]

hey there, does anybody knows the color depth of minecraft skins?

256? 16b? 32b? 64b?

[echo basalt]

It's literally a base64 encoded png

8 bit / channel

[solar mauve]

256 so?

[echo basalt]

256 yea

[solar mauve]

ty

[analog thicket]

The middle of a block is 0.5, 0.5, 0.5 right?

[opal juniper]

block pos + that yes

[analog thicket]

Alright thanks

[regal scaffold]

What language are plugin descriptions written in for spigot forums

Any tips on tools to use to make them look nicer?

[solar mauve]

how you are getting the packet? (from netty, from start)

you need to specify the string size in bytebuf , you don't know where is to end the reading data, thats why you are getting the exception, write an int, then, write data, specify the string length in that int, and read it like that, juts like mc:

1. get the bytebuf
2. read length
3. read bytes
4. instantiate the new string

    public String readString() {

        int size = readVarInt();

        if (size < 0) {
            throw new DecoderException("The received encoded string buffer length is less than zero!");
        }

        byte[] bytes = new byte[size];
        buffer.readBytes(bytes, 0, size);

        return new String(bytes, Charsets.UTF_8);
    }

[undone yarrow]

Is it possible to detect impact when mounting an animal? For example, you're riding a vehicle that goes fast, but then you hit it against a blockade, and it should go boom.

I guess it's possible to detect the change in velocity

but what about dismounting and braking?

[dry yacht]

That's a really interesting question, but I sadly found no answer within the bukkit API, even after some digging. The only way I found was using NMS. CraftWorld#getHandle returns you the WorldServer, which offers a method called getFluid. You pass a block-position, it passes you the Fluid instance. And that then has a method called isEmpty. If you negate that, you know whether the block is water or not, simple and without all these edge-cases. Calling this on the eye-location works a treat.

So you either have to stick to your method of checking and maintain the list (adding new blocks as they come in with new versions), or try to access the information that way.

[rare flicker]

i'll stick with my list then , this function is for a library and making it version dependant because of nms would be pretty annoying

might try reflection though

[dry yacht]

Just wanted to let you know about the alternative. The Material enum constants you're checking on are bound to >= 1.13 anyways, and the API I mentioned has been there since (at least) then. Reflect would work out.

Maybe it's really better to maintain that small list. Depends on how comfortable and efficient you are with reflect.

[rare flicker]

never really tried but it ain't black magic, just need to call functions while blind is all.
ideally i try reflection in a try catch and use the hardcoded list + log a warn on fail

[vernal oasis]

I made a forum post, Choco replied but the answer does not work.

I'm working on a Plugin for 1.19.3 but I can't figure out how to determine the advancement type, Task, Goal, and Challenge. I've tried many things but they've not worked, and every time I think I have a solution, it's a deprecated action from an older version.

I need to getType() function, or something that can reliably get the Advancement type, not hard coded as I plan on adding custom advancements.

[verbal slate]

Hey guys! Who knows how to do it right? I want certain actions to take place when the player places an item in the EquipmentSlot. I understood that this should be done in PlayerItemHeldEvent, but I do not know how to get the value of the main hand slot in this case.

    @EventHandler
    public void onPlayerHeldItem(PlayerItemHeldEvent e) {
        Player p = e.getPlayer();
        int slot = e.getNewSlot();
        ItemStack is = p.getInventory().getItem(e.getNewSlot());
        if (slot == 5 || slot == 6 || slot == 7 || slot == 8) {
            if (Main.isArtifact(is)) {
                if (Main.isArtifactOwner(is, p.getUniqueId().toString())) {
                    Artifact art = null;
                    for (Map.Entry<String, Artifact> set : Main.getArtifacts().entrySet()) {
                        if (set.getKey().contains(is.getItemMeta().getDisplayName())) {
                            art = set.getValue();
                        }
                    }
                    if (art != null) {
                        for (PotionEffect effect : art.getEffects()) {
                            if (!p.hasPotionEffect(effect.getType())) {
                                p.addPotionEffect(effect);
                            }
                        }
                    } else {
                        p.sendMessage(prefix + Main.getConfigString("messages.noOwner"));
                        is.setAmount(0);
                    }
                } else {
                    if (Main.isDeprecated(is)) {
                        p.sendMessage(prefix + Main.getConfigString("messages.deprecatedArtifact"));
                        is.setAmount(0);
                    }
                }
            }
        }
    }

[remote swallow]

player.getInventory().getItemInMainHand()

[verbal slate]

and check whether it converges with is?

[fickle ivy]

Hey, Need some advice. Got this functino ``` private boolean checkWorld(String world) {
ConfigUtilities config = new ConfigUtilities(plugin, "coords.yml");
for (String key : config.getConfig().getConfigurationSection("stops").getKeys(false)) {
String worldb = config.getConfig().getString("stops." + key + ".Location.world");
if (worldb.equalsIgnoreCase(world)) {

        }else{

        }


    }
    return true;
}```   It cycles through a list of places stored in a coords file.  What I am planning is send EACH location to another class to check to see if the location is within x blocks of player.  In the end, if NO locations are within x blocks of the player it will add the players location to the coords file.  What would be the best way to do that?  Should I just define a string then have it change it if the distance class returns true or some other way?

or maybe a boolean?

[verbal slate]

OK, I did a check for the right slots. But now how to check that the item is in a certain EquipmentSlot?

Conditionally, I can get an EquipmentSlot from an Artifact object, and I need to check its match with the item slot

oh, got it

                        EquipmentSlot slot = art.getEquipmentSlot();
                        for (PotionEffect effect : art.getEffects()) {
                            if (!p.hasPotionEffect(effect.getType())) {
                                if (p.getInventory().getItem(slot).equals(isNew)) {
                                    p.addPotionEffect(effect);
                                }
                            }
                        }

is it some kind of Map?

[ornate patio]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Tag.html#ITEMS_FISHES

[rough ibex]

Ah

[eternal oxide]

You would need to get the actual Tag from getValues()

[ornate patio]

ah okay

thanks

also another quick question

lets say i have a config file like so:

egg-recipes:
    built-in:
        squid: ink_sac
        silverfish: cobblestone
        zombie_villager: diamond_block
        villager: emerald_block
        wandering_trader: lead
        ...

is this an efficient way to loop through each mob-item relationship:

for (String spawnEggName : plugin.getConfig().getConfigurationSection("egg-recipes.built-in").getKeys(true)) {
    String ingredientName = plugin.getConfig().getString("egg-recipes.built-in." + spawnEggName);
}

it looks a little cursed to me idk

i feel like i should be able to loop through key value pairs like a map

[eternal oxide]

no need to pull from teh config for each one, you are using getKeys(true) so it contains a full sub map

all you are getting though is teh built-in

ah yep

ignore that

yes it would work but you are doing it wrong by pulling each one from the config

[ornate patio]

wait can you explain what’s the proper way to do it then

[eternal oxide]

String ingredientName = spawnEggName.getValue();

your getKeys(true) will not return a string

it will return a map/section

for (MemorySection spawnEggs : plugin.getConfig().getConfigurationSection("egg-recipes.built-in").getKeys(true)) {
    String eggName = spawnEggs.getKey();
    String ingredientName = spawnEggs.getValue();
    // do stuff
}```

[remote swallow]

shouldnt you use getKeys false in that case

and that should return a string key

oh wait i didnt read enough

ignore me

[ornate patio]

Oh okay

Thanks

[ornate patio]

i'm getting red underlines

wrong method?

i found that I can do this instead:
Map.Entry<String, Object> spawnEggs : plugin.getConfig().getConfigurationSection("egg-recipes.built-in").getValues(true).entrySet()

[river oracle]

... learn Java please I'll help in the future

[inland siren]

anyone know if there’s some kind of in depth documentation on how the transaction system changed in 1.19

[ornate patio]

me?

i been using java for years lmao, i know what the error means

[warped shell]

Is there a way to set the world of a bounding box? I see now way to change what world it spawns in

[ornate patio]

im just letting him know that the method he told me to use isn't correct

[swift karma]

any packet wizards here? stuck on how to use PacketPlayOutEntityMetadata in 1.19.3

[ornate patio]

i ended up using reflection for this, couldn't really find a valueOf method or anything

tag = (Tag<Material>) Tag.class.getDeclaredField(itemString.toUpperCase()).get(null);

[ornate patio]

yeah i checked docs ofc

also since when were blank spawn eggs removed?

[marsh burrow]

Hey would anyone know why ItemMeta.setCustomModelData aint showing up as a method of me in 1.17.1?

[sullen marlin]

Registry maybe?

[ornate patio]

how would that work

if its a little complicated its fine cause what i have works

[unique gate]

I'm running a 1.8 spigot server. Sometimes I change the biome over a certain area using the worldedit api. The problem is that when the biome is changed, the chunks aren't updated, so the players either have to relog or go out of render distance and back in to see the chunks with the new biome. So my question is how can I update chunks for nearby players?

I've tried to use the PacketPlayOutMapChunk packet, but it's causing chunk errors that make the blocks invisible

Player player = hippoPlayer.getPlayer();
net.minecraft.server.v1_8_R3.Chunk nmsChunk = ((CraftWorld) world).getHandle().getChunkAt(player.getLocation().getBlockX(), player.getLocation().getBlockZ());
PacketPlayOutMapChunk packet = new PacketPlayOutMapChunk(nmsChunk, true, 65535);
((CraftPlayer)hippoPlayer.getPlayer()).getHandle().playerConnection.sendPacket(packet);```

[worldly ingot]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/pull-requests/733/overview implements Registry#getTag(NamespacedKey), so not currently possible, no

though with that being said, you'd have to check each Registry for your Tag, unless you know which Registry you're wanting to look in

In the interm @ornate patio you can use https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Bukkit.html#getTag(java.lang.String,org.bukkit.NamespacedKey,java.lang.Class)

[ornate patio]

hmm i'll look into it

[quaint mantle]

Player player = Bukkit.getPlayer(name);

will the code i posted above return a Player object with its uuid?

even if the player is offline?

i am trying to get a player object from command.

[drowsy helm]

no

Bukkit.getOfflinePlayer

[quaint mantle]

but

https://imgur.com/sn2ERY9

it has a line going through it.

can i still use it?

[drowsy helm]

yeah its deprecated

you can still use but it might be removed in later versions

[quaint mantle]

its for 1.19.3, is it okay to use?

[drowsy helm]

should be

[quaint mantle]

ok.

[drowsy helm]

if you want to avoid deprecation you can use mojang api

but thats a pain in the ass

[quaint mantle]

i dont exactly need the player uuid if the player has never joined.

and another question, what does it return if the player has never joined?

is the OfflinePlayer object null?

or is the uuid field null?

i just need the uuid.

[drowsy helm]

if you just need the uuid use mojang api

[quaint mantle]

i could but it is rate-limited.

dont know how many people will use it.

besides, i dont exactly need it if the player has never joined the server before.

[wet breach]

Is it really difficult to just look at the javadocs and read?

Instead of asking a million questions

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[wet breach]

Reason get player by name is deprecated isnt because it will be removed as it wont. It is deprecated to warn players can change their name

[sacred wyvern]

Is there a way to add tab whitespace to a message sent to the player?

\t gives an odd character

[rough ibex]

What does it show?

If it shows some dotted box, that is on purpose because of the font, you will need to use 4 spaces

[sacred wyvern]

Ya pretty much the "Character not found" box. Ah ok, I was hoping to use it to align multiple data sets on multiple lines.

[rough ibex]

Yeah, there's no default space for the tab

you can manually do it with a font resource pack but that's too much work

also the tab is a static amount of space, it doesn't adapt

[sacred wyvern]

Ya I am having to look at a Resource Packs right now. I have a command system built for my plugin but I'd like to get a custom GUI into place without requiring mods.

[rough ibex]

well, a GUI doesnt normally require a tab character

[sacred wyvern]

True, I'm starting with commands for now to get the initial admin framework in place and then hoping to be able to use GUI's to create an easier interface.

It needs text inputs though and that seems to be a tricky thing

[sick epoch]

Hello ! i have a problem with my Java plugin of break block event ^^ can anyone help me ?

The Error
Jobs v1.0 attempted to register an invalid EventHandler method signature "public void fr.clemkill.legendjobs.Listeners.LumberJack.PlayerHarvestBlockEvent(org.bukkit.event.player.PlayerHarvestBlockEvent,org.bukkit.block.Block,java.util.List)" in class fr.clemkill.legendjobs.Listeners.LumberJack

The code :
public class LumberJack implements Listener {

@EventHandler
public void PlayerHarvestBlockEvent(PlayerHarvestBlockEvent e, Block harvestedBlock, List itemsHarvested){

    Player player = e.getPlayer();
    Material bloc = Material.OAK_LOG;

    if (e.getHarvestedBlock().getType() == bloc) {

        player.sendMessage("Vous gagnez 1 xp");

    }

}

}

Main class

public final class LegendJobs extends JavaPlugin {

@Override
public void onEnable() {
    // Plugin startup logic
    System.out.print("Enabling Jobs...");
    getCommand("jobs").setExecutor(new jobsCmd(this));
    getServer().getPluginManager().registerEvents(new LumberJack(),this);
}

@Override
public void onDisable() {
    // Plugin shutdown logic
}

}

Thank youuu 🙂

@everyone

[analog thicket]

Could you put in THIS

[weak kayak]

it looks like you have too many parameters in your method. remove harvestedBlock and itemsHarvested

[ivory sleet]

```java
//CODE

This?

[tawdry echo]

when premium player change their nickname then at offline mode server he still have same uuid?

[ivory sleet]

No not guaranteed

Offline servers generally need to implement their own login system as uuid is no longer really reliable

[frank kettle]

Offline mode is based on name

Unless you have some system that gets their real uuid if they have premium, then u will be safe

[analog thicket]

Yep that

[tawdry echo]

you have any example of this system, i mean api for that

[frank kettle]

No

But search on spigot for login systems

If I recall correctly, some of them had something around that

[vital sandal]

just create it :d

PLayerLoginListener
saving player data to config/database

[hazy parrot]

You can also look at the 3rd block of the uuid. If it starts with a 4 the uuid is a Online uuid, if it starts with 3 it is offline

[ivory sleet]

The problem is that this is not a guarantee, sure spigot uses that, but it’s changeable

[quaint mantle]

you dont specify the block in the thing

it should be

onHarvest(PlayerHarvestBlockEvent e)

[fickle ivy]

Just curious what it takes to get help here. I have asked several times and each time my question goes ignored yet everyone else's get answered pretty quick.

[regal scaffold]

How can I compare if a object I saved as a serialized PDC is the same as the current object as in it has the same fields.

I'm thinking like, what if I change the PDC object in the future, if I try to access a field that wasn't originally there it would give big errors

[remote swallow]

its either we dont notice it or dont know the answer to it

[regal scaffold]

Nah ebic, mostly we don't want to.... makes total sense

We couldn't possibly miss the question or not know the answer, that would be outrageous

I guess we gotta go back 10 hours

[remote swallow]

im guessing this

ope

he left

[regal scaffold]

LOL

f

Mans was wondering why no one answered his question 10 hours ago

[remote swallow]

i think the better response to that was to, realise no one answered after 30 min, so just reply to the message saying "anyone know"

[regal scaffold]

It's ok to bump stuff... no one minds unless you're dumb aobut it

[remote swallow]

yeah

[regal scaffold]

bump @remote swallow

[remote swallow]

[regal scaffold]

It's been 3 minutes, I'm entitled

😆

[remote swallow]

im very confused of what that means, what you trying to do with that

[regal scaffold]

Well, I have a object that I store inside a pdc

but if I add something new to the object

The current existing pdcs obviously don't have that data

so big errors

[remote swallow]

ohhhhh that makes sense

[regal scaffold]

So either I need a way to ?convert it? but for that I need to know that it's different

So how do I do either of those lol

[torpid blaze]

Hey,
I am trying to code a minigame with multiple maps which properies I want to save in a yml file. Each may has a name so I save them as a HashMap for easy use.

My Problem is now, that when I try to get all saved maps, I often get null in return even though I have samed one. Also if I try to only get the name using getKeys.

Anyone any idea what I am doing wrong?

[regal scaffold]

Are you sure the path is right?

[torpid blaze]

yea

[regal scaffold]

I would give you some debugging steps but I would wait for someone that knows more about FileConfiguration to speak cause they'll probably solve it way quicker

[torpid blaze]

It is also strange because after restarting the server, I works for one time and after updating something of the maps, it doesn't

[remote swallow]

if its only modified once you could add a boolean that you can read to know if something happend, or if its a set value that you could get another time and those fields are modified you just check if its different

[torpid blaze]

ok, thx anyway

[regal scaffold]

I guess instead of a boolean, I could add a "version"

[remote swallow]

yeah

[regal scaffold]

That seems more complicated

Than just.... making sure it doesn't change

xd

[remote swallow]

are you using a configuration serializer?

[torpid blaze]

I don't think so

[wet breach]

I assume something will be null of you expect certain data that isnt there

[regal scaffold]

Indeed

[wet breach]

Then that is your indicator it is different

[torpid blaze]

My custom Objects are ConfigurationSerializable

[regal scaffold]

Ebic suggested a boolean hasChanged but I thought a int version would be more adaptive

So like a version for the object pdc

And then I would know what to add

[wet breach]

Adding a version identifier would be better and smart in the beginning

[remote swallow]

That Is My Map and Position object

[wet breach]

The only thing that will be hard about versioning is whether or not you want to continue supporting old data or just wipe it completely if its too old

[regal scaffold]

Well, I just need to know what to add, I guess just if something is null, initialize it to default would be good enough

[torpid blaze]

I need the Position because I don't want to save the map.
I thought is easier that way

[regal scaffold]

Now that you mentioend it

But another question, if I have a Class that I'm serializing, and there's a field in that that is not primite but another Class that I need to serialize, do I need to add serialization stuff to the subclass too?

[wet breach]

Well from one version to the next its not hard. But over time you end up with a class for various conversions of the data lol

[regal scaffold]

As in

class Ser1 implements ConfigurationSerializable {

  private Ser2 ser2;

}

class Ser2 {}

[remote swallow]

looking at it the Position object is null, somewhere the Position var is null

[torpid blaze]

I don't think that that is the problem

I save the yaw and pitch as null when not set

[remote swallow]

if the obj wasnt null but the values were it would still add the x,y,z fields

[torpid blaze]

yea

I don't understand

at my map I didn't set a spawn or other values yet

so they are null

[remote swallow]

that would be why theyre null

What a smart plugin

[remote swallow]

im pretty sure my brain hasnt turned on yet, so ive got no idea whats going on. Best to wait for a few others to help

[wet breach]

You can only have one null value on the set as the set doesnt allow duplicate values

If you do so it makes it all null

[torpid blaze]

ok, no. I think there should be no null value in the Set

[wet breach]

You said you use null

Which you shouldnt

[torpid blaze]

because what should be null. Max the value of a map key could be null and they aren't in a set

[torpid blaze]

I miss understood

I tried just again and it is like this:
After reloading the server, the getSections or getKeys method is not returning null until I change something at the map values and save it into the file

and when reloading again, it is working again for one time

That makes no sence

[eternal oxide]

?paste show some code

[undone axle]

https://paste.md-5.net/

[wet breach]

Dont use server reload especially if your plugin isnt coded to handle it

You obviously dont check if the cpnfig in memory is null as that is what a server reload does. You also dont check if the references you have are suddenly null as well

Which is what will happen if you reload

[torpid blaze]

I already did above

https://paste.md-5.net/uwuqenujiy.cpp
https://paste.md-5.net/avatesayar.cpp

[torpid blaze]

and here some images

[torpid blaze]

ok, that makes sence

but why should the config in memory be different from the one in the file?

[eternal oxide]

why are you streaming into a new Map when you call the constructor?

just pass bs

[torpid blaze]

where?

[eternal oxide]

102 and 112

map.put("blocks", blocks);

[torpid blaze]

Because yml doesn't want to save Material properly

[wet breach]

Its not about being different its about object references no longer being valid. If the reference isnt valid it returns null regardless of what you do. Now it could be your plugin is coded in such a way that something causes the plugin to refresh references or obtain new ones. Thus the random failures with reloads

[torpid blaze]

?paste

[undone axle]

https://paste.md-5.net/

[torpid blaze]

https://paste.md-5.net/jiqonunide.cs

Thats my Config Class

How could it happen that the reference is null?

[wet breach]

Because the server gets rid of them

But looking at your code it makes sense now with all the static usage

Remove the statics and go learn about static so you know when to use them and to properly use them. Otherwise all its going to do is cause you problems like you are having

Does BlockBreakEvent trigger in ANY case that the block will get broken?

Piston? Mobs?

[eternal oxide]

Called when a block is broken by a player.

says in the javadoc

[wet breach]

Piston has its own event

And so do mobs

[regal scaffold]

So if I want to make a specific block unbreakable by all those things

I need to check for each one individually?

[eternal oxide]

yes

[regal scaffold]

No way to add "invincibility" to it otherwise

Alright

ty

[wet breach]

You could just set the tag

[regal scaffold]

?

[eternal oxide]

tag?

[regal scaffold]

You have caught my attention

[wet breach]

Pretty sure there is one otherwise mojang would have to code fpr all those things too for bedrock

Let me checj

[eternal oxide]

bedrock is a hardness value in the Material data

[regal scaffold]

But like, I want only a specific player to break it just want to prevent everything else

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[eternal oxide]

Modifying teh hardness of a Block is possible, but it is not easy and requires you use reflection

[regal scaffold]

Is it really worth it?

Cause I still need players to be able to break it

[eternal oxide]

imho no

[regal scaffold]

So I think events is the way to go

[eternal oxide]

the client will still ghost teh block at times

[regal scaffold]

Why can't all the events be in one place...

[remote swallow]

they are technically

[regal scaffold]

Well....

[remote swallow]

just search for Event and you have all of them

[eternal oxide]

it was either mfnalex or 7smile7 who wrote a class for modifying Material data but it's not 100% reliable

[regal scaffold]

Yeah it's fien I'll just check all the events in the game ig

I have a question tho

public class BlockExplodeEvent
extends BlockEvent
implements Cancellable
Called when a block explodes

Does that specifically mean tnt

[eternal oxide]

no

[regal scaffold]

Cause technically only block that explodes is tnt

[eternal oxide]

explode is for things like beds in the nether

[regal scaffold]

Oh

[remote swallow]

entity explode event is tnt, creepers etc

[eternal oxide]

tnt block doesn;t explode

[wet breach]

There is actually a few block tags you can use to make it immune to mobs and then of you set hardness level to -1 nothing can break it

[regal scaffold]

Wait so, what are the ways a block can be broken

Players

Creeper

[wet breach]

Then all you have to do is check of if its your block and the right player and let it break

[terse ore]

enderman counts?

[regal scaffold]

Chest

So no

[remote swallow]

block break event, Entities/tnt, endermen, pistons

[regal scaffold]

Frost I like your idea but not sure how to implement it

Safe way is events

[wet breach]

If you set the hardness level to -1 you dpnt have to check for all those things lol

[regal scaffold]

I mean I guess

Do I just check for BlockBreakEvent with hardness at -1?

I thought it wouldn't even be triggered if the Block can't be broken at all

[wet breach]

Blockdamageevent still gets thrown

[regal scaffold]

What if a creeper blows the block up while the player is trying to break it

Cause I assume aftert blockdamageEvent gets thrown, I would set the hardness back up to allow it to be broken if it's a player

[wet breach]

Nothing in the game can break a block with hardness being negative exception being dragon and withers unless you set the block tags for it to be immune

[regal scaffold]

But eventually I need the player to be able to break it

I just need to make it inmune to everything else

[wet breach]

Yes and so all you need is blockdamage event

Check the stage and of its the last stage or time or whatever and its your block and the right player allow it to break

[regal scaffold]

What if I set it to -1 and make a button inside the GUI that's called "pickup"

[wet breach]

You can simulate it breaking by just removing it and spawning it on the ground as an item at the same time

[regal scaffold]

So I make it fully invincible unless you press the button

[wet breach]

You could do that too

[regal scaffold]

Is hardness a tag for the block or item?

Like if I set it to the chest, does it have to be placed?

Or I can set it as a nbttag

[wet breach]

Yes it has to be placed to modify it. Unfortunately will require some nms

[regal scaffold]

So there's no way to set the hardness while it's an item in inventory

[wet breach]

No, because that gets set when the block is created

[regal scaffold]

Gotcha

Alright, ty

[wet breach]

Should say generated

The game doesnt look at the item for it it just pulls the values from the defaults for it

But you can modify its nbt data for it

[hazy parrot]

You can just set pdc flag to item and set hardness when placed according to that

[wet breach]

Anyways time to drive home

[regal scaffold]

That' is true

Damn i like that solution

But this still requires nms

And so far I haven't needed it

[river oracle]

Just go for it :P

[regal scaffold]

I'm trying to make a command give an item to a player.

    @Subcommand("giveitem")
    @CommandCompletion("@players @range:1-64")
    public static void onGiveItem(CommandSender sender, @Optional String playerName, @Optional Integer amount) {}

And I was thinking that I need to do a bunch of checks to make sure the player exists, the item amount and such

Does ACF have a way to simplify this?

[tardy delta]

why is the player optional

do Player target

[regal scaffold]

Give to yourself if no player

[tardy delta]

ah

[regal scaffold]

And give 1 if no number

[tardy delta]

atleast use a Player object

[regal scaffold]

Yes but

What if the name provided isn't a player

Big errors

So what I'm asking is, is there a way to check this using ACF or do I need to do ifs inside the command

        Player player = null;
        if (playerName == null && sender instanceof Player){
            player = (Player) sender;
        }

stuff like that

[remote swallow]

why use command sender then

if you just get a player instance

[tardy delta]

you will get a syntax error when you did not provide a player name

[regal scaffold]

Console?

It's actually something like this if I'm not wrong

        if (playerName == null && sender instanceof Player){
            player = (Player) sender;
        }
        if (playerName == null & !(sender instanceof Player)) {
            // no player
            return;
        }

        if (playerName != null) {
            player = Bukkit.getPlayer(playerName);
            if (player == null) {
                //player not found
                return;
            }
        }

What I'm wondering is if ACF has a way to simply that

Or do I need to do all that every time I want to have an @optional player in the command

[regal scaffold]

Oh

[remote swallow]

if(playerName == null) return;
if (!(sender instanceof Player player)) return;
player.doSomething();

[regal scaffold]

But this

So I need to change the declaration

[tardy delta]

idk i havent been working with acf for half a year

just ask in their discord ig

[regal scaffold]

I mean

@lost matrix you probably know this but I asked in there anyways

[hazy parrot]

Just have optional player

And if player is null, it is executed by console/command block?

[regal scaffold]

Well, if it's executed by console should have a player

I think maybe separating

Is better for this

[hazy parrot]

What

[regal scaffold]

Only allow Player sender

[hazy parrot]

Console is not a player

[regal scaffold]

I mean, if sent by console, player shouldn't be optional

I'm gonna split it

And use @optional Player

[quaint mantle]

the way you had it originally was better than splitting it, just return early if the target is null and the sender is not a player. Otherwise set target = (Player) sender if the target is null and that will cover both cases (target will be the player you specify if it isn't null, player sender if it is).

Not sure if there are contexts in ACF like there are in some other command frameworks; those will let you create a context to set the target to be the sender automatically if the target is null

[regal scaffold]

Yeah indeed, I kept investigating and got it

Contexts are great

If I use

getTargetBlockExact()
``` and I want to check if the block is a Chest I need to getState right?

sender.getTargetBlockExact(6).getState() instanceof Chest

I still can't understand really the difference between Block, BlockState and BlockData

Whats the question?

[regal scaffold]

    @Subcommand("giveitem")
    @Syntax("<player> <amount>")
    @Description("Gives a specified player a number of chest items")
    @CommandCompletion("@players @range:1-64")
    public static void onGiveItem(CommandSender sender, @Optional Player playerName, @Optional @Default("1") Integer amount) {

You can use Player in ACF as an argument.

Use OnlinePlayer

[regal scaffold]

What about optional default player?

[lost matrix]

Optional means the value is null if not provided

[ivory sleet]

like plugin dev income?

[regal scaffold]

I want to default to the sender if no player is provided

[lost matrix]

I would do a simple null check

[regal scaffold]

Ok cool that's how I was doing it

Thought acf had something else fancy

Thanks smile

[lost matrix]

It has but i think you should start with just a simple null check

[regal scaffold]

Alright cool, thanks

block is well, block. BlockData is data inside of block, for example how many bites of cake is left, and state is well explained in docs

Represents a captured state of a block, which will not change automatically.

So if I want a chest I just want the Block

i assume that good percentage of guys here learned or started learning java because of mc

[hazy parrot]

nah, you are doing it right with block state

[quaint mantle]

mc is literally how I have my current job

It's not related at all to mc but I learned a lot of core concepts from plugins/mods

[hazy parrot]

its always easier to learn something if you are interested in doing it
